Operations research (OR) is a multidisciplinary field that employs mathematical modeling, optimization techniques, and statistical analysis to solve complex decision-making problems. By formulating problems, developing mathematical models, and applying optimization algorithms, OR helps organizations make informed decisions to improve efficiency, resource allocation, and overall performance across diverse domains such as manufacturing, transportation, healthcare, finance, and logistics. Through methods like simulation, queuing theory, and decision analysis, OR enables organizations to tackle challenges ranging from inventory management and supply chain optimization to project scheduling and strategic planning, ultimately driving innovation and competitiveness in today's dynamic business environment.
